In prep for a post-mortem on this project, I wanted to start a page of issues that have occurred:

IssueAction TakenFuture Actions

GPS timing oddWidened range of acceptable time lagUpgrade software on all receivers (3.0-3.7 -> 3.9)
200m DSM needed 150m GPS, but it diedChanged to use 250m? GPSNone?
Qsoil reading 0x8000none

Fix

Check connector at tear-down

CSAT3 broken upon installationRepaired at CSI – bad coax cable in head/boxUnknown - new handling procedure?
XBee mote not reliable over 3m distanceChanged to serial mote (tried changing power)Change to all Bluetooth motes?
